Hello, Jes Lee. I am the instructor. First of all, thank you so much for taking the course <React Master Class: Part 1 - Mastering the Essence of Rendering and Design through Missions> and for leaving such a high-quality review. Your thoughtful feedback is a great source of strength for me. It is very impressive that you gained inspiration for complex UI design through the principles of React, a modern frontend framework, even though your current work environment is centered around JSP and jQuery. As an educator, I feel a great sense of accomplishment because you perfectly grasped the core intent of my lecture—that the "essence of rendering" and "structural considerations" are more important than the type of tools used. I am especially glad to hear that the missions I prepared helped you stay engaged. I sincerely support your passionate learning and new endeavors. If there are any additional courses in our curriculum that you wish to take, please feel free to contact me at the email address below. I will send you a discount coupon as soon as I check your message. Inquiry Email: jeony0535@naver.com Thank you once again for taking the time to leave such warm and insightful words.
